Answer:
A RNA polymerase separates the hydrogen bases of a gene to produce a strand of messenger RNA, which leaves to nucleus. When a ribosome attaches itself to the messenger RNA, it reads the RNA 3 bases at a time to build amino acids which are then folded into proteins.
More explained process:
Note: The description below will explain the process of “protein synthesis”, in which the mRNA (messenger RNA) takes part of.
In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids. [ For example, the bases are AUC, the corresponding amino acid will be isoleucine (Ile). Next, the tRNA molecules carry the amino acids to mRNA, reads the RNA 3 bases at a time to build an amino acid chain which are then folded into proteins.
Answer:
INDEPENDENT VARIABLE: COCONUT JUICE
DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME
CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER
CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER
Explanation:
- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.
- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.
- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.
- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.
Answer:
E
Explanation:
The lack of organelles in prokaryotes means that the basic cellular functions are different in prokaryotes than in eukaryotes.
